1. The problem statement, all variables and given/known data The first particle A is starting at origin and it has a velocity vector with magnitude 10km/h and moves at an angle of 30 degrees relative to y axis. The second particle B is starting at (0,5) and it has velocity vector with magnitude 8km/h and moves at an agle of 60 degrees relative to y axis. Will these 2 particles colide, and if not, what is the minimal distance they will be at? 2. Relevant equations 3. The attempt at a solution I found the velocity vectors with given angles/magnitudes. I'm not sure what to do now.
